Lead smelting — Wikipedia Republished // WIKI 2

Secondary lead processing Most of the lead produced comes from secondary sources. Lead scrap includes lead-acid batteries, cable coverings, pipes, sheets and lead coated, or terne bearing, metals. Solder, product waste and dross may also be recovered for its small lead content.

Lead Smelting - an overview ScienceDirect Topics

Secondary lead smelting is such a hazardous process that priority should be given to automation of the transport and oven-filling phases. The preparation of all metal pigments, which is very hazardous when done by hand, becomes far less dangerous in closed, automated systems. Instead of dust-producing powders, liquid premixes are preferred.
